The spring constant = 31 N/m, the spring's compression is 0.04 m, the ball's mass is 0.017 kg, the height of the ramp is 10 cm, theta is 35 °and the top of the table is 0.9 m above the floor. With what speed will the ball hit the floor?

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
